Samir Abdelrehim

An Electrical Engineer with a Master's degree in Electronics Engineering from the University of Southern Denmark. My primary areas of interest and expertise lie in Electrical power engineering, power electronics, and Wide Band Gap semiconductors physics and design. With a solid foundation in both academia and industry, I have hands-on experience in the design, development and testing of GaN/SiC-based fi eld effect transistors. My passion for scientific research converges with my keen interest in the power electronics industry. Seeking an opportunity to bridge these realms and make meaningful contributions.

• Master Thesis
  University
  of Southern Denmark
  01/2023 - 06/2023
  -Conducted a comprehensive study on "A novel design of an Advanced GaN CAVET for High‑Power Applications" with a focus on improving on‑state resistance without compromising breakdown voltage.
  -Achieved a remarkable 32.5% reduction in on‑state resistance and validated a Figure of Merit (BFOM) as high as 3.18 GW/cm², while considering cost-effectiveness and fabrication complexity.
  -Received a perfect score of 12 on a 12‑point grading scale, signifying outstanding academic performance.
  -Associated Skills: TCAD simulation ‑ Power semiconductor characterization ‑ Extensive experience with Lateral and Vertical GaN devices in GaN CAVETs physics and design optimization.
• Intern
  Danfoss Drives
  09/2022 - 01/2023
  -Mapping of power loss in a 30 kW variable frequency drive to improve the lifetime efficiency of Danfoss drives.
  -Managed to map 90% of the losses by following a mathematical model (IEC60081), simulating the system on Power sim, and conducting lab measurements.
  -Cooperated with other team members to evaluate and document the results obtained from measurement.
  -Associated skills: PSIM power electronics simulation ‑ Variable Frequency Drives (VFDs) ‑ High voltage measurements ‑ Power converters topologies ‑ Power loss analysis ‑Teamwork.
• Student Worker
  Schneider Electric
  08/2022 - 02/2023
  -Validating SiC MOSFETs from different vendors for Schneiders' next-generation SiC‑friendly three-phase converters.
  - Conducted double pulse tests to analyze switching behavior and assess switching and conduction power losses.
  -The SiC MOSFET to be used in Schneider next next-generation converters was chosen based on the results of this project.
  - Associated Skills: High voltage testing‑Circuit Design ‑ Duple pulse testing ‑Testing and validation of WBG MOSFETs
